In the above, we use the yiic shell command to interact with our
skeleton application. At the prompt, we execute two sub-commands: model User tbl_user
and crud User. The former generates a model class named User for the tbl_user table,
while the latter analyzes the User model and generates the code implementing
the corresponding CRUD operations.

Note: You may encounter errors like "...could not find driver", even
though the requirement checker shows you have already enabled PDO
and the corresponding PDO driver. If this happens, you may try
to run the yiic tool as follows,

% php -c path/to/php.ini protected/yiic.php shell

where path/to/php.ini represents the correct PHP ini file.

Let's enjoy our work by browsing the following URL:

http://hostname/testdrive/index.php?r=user

This will display a list of user entries in the tbl_user table.

Click the Create User button on the page. We will be brought to the login
page if we have not logged in before. After logged in, we see
an input form that allows us to add a new user entry. Complete the form and
click on the Create button. If there is any input error, a nice error
prompt will show up which prevents us from saving the input. Back to the
user list page, we should see the newly added user appearing in the list.

Repeat the above steps to add more users. Notice that user list page
will automatically paginate the user entries if there are too many to be
displayed in one page.

If we login as an administrator using admin/admin, we can view the user
admin page with the following URL:

http://hostname/testdrive/index.php?r=user/admin

This will show us the user entries in a nice tabular format. We can click on the table
header cells to sort the corresponding columns. We can click on the buttons
on each row of data to view, update or delete the corresponding row of data.
We can browse different pages. We can also filter and search to look for
the data we are interested in.

All these nice features come without requiring us to write a single line
of code!
